So were on the chapter where we factor polynomials by reversing the process and using zero factor property. Here are the questions with my answers...can someone check for me??

1. 12x^2=8x

12x^2-8x=0

4x(3x-2)=0

ANSWER= x=0 x=2/3

2. x(3x-2)-7(3x-2)=0

(x-7)(3x-2)=0

x-7=0 3x-2=0

ANSWER= x=7 x=2/3

3. x(x+9)=2(x+9)

x(x+9)-2(x+9)=0

(x-2)(x+9)=0

ANSWER= x=2 x=-9

Did I do these correct?
